Product detail

The GS3150 Cross Roller Guide is a precision-engineered linear motion solution designed for applications demanding the highest levels of accuracy and rigidity in a compact footprint. Its unique design features cylindrical rollers arranged in a 90° V-groove cross pattern between the rail and the base, enabling it to withstand heavy loads from all directions—radial, reverse radial, and lateral. This makes the GS3150 an ideal, all-in-one choice for precision automation, measurement equipment, and semiconductor manufacturing where space is limited and performance is critical.
